THE INTERNET
BACKGROUND
The Internet is the world’s largest computer network. It is a network of networks. The networks of various organizations as well as the computers of individuals are linked together via the internet.
The Intern was originated by the Advanced Research Projects Agency (ARPA) of the Department for Defense (DOD) to allow four universities doing research for the DOD to exchange information. At the time (1969), the network was called ARPANET. One of the results of how it was originated is that there is no central control of the Internet. The DOD wanted to ensure that in the network couldn’t be taken out by an attack on the control center. The internet now has hundreds of millions of users, but there is still no central control.
SERVICES
There are many services available on the internet. Some of them are:
* E-mail
* Newsgroups
* Chat rooms
* Instant messaging
* The World Wide Web (often just called the Web)
The web is the most widely used service on the internet which is why it is confused with being the Internet. However the web and the internet are not synonymous. The Web is just one of the services available on the Web.

E-business on tourism accounted for $13 billion in 1999 (Forrester Research 1999). The online travel market is experiencing explosive growth, and is projected to go to $30 billion this year. It is already estimated that by year 2003 over 30% of online sales will be generated by online travel alone, including actual travel products as well as advertising earned by travel-oriented sites. The number of travelers who use the Internet for travel-related and other purposes tops 70 million, half of which consult the Internet to get information on destinations or to check prices and schedules (Travel Industry Association of America 1999). The number of travelers booking online has soared by more than 80 percent to 11 million in the last year (PhoCusWright 1999). Travel remains one of the most popular e-commerce categories, with 45 percent of online buyers saying they purchased travel online. This is outpaced only by books at 54 percent.

...Rodriguez, Marione Thea B. Block 11 BS Biochemistry What is the latest trend in connecting to the internet in the Philippines? One of the various ways to connect to the internet is through fiber optic technology. It delivers laser-generated pulses of light on strands of glass fibers. Recently, Globe Telecom Inc. is laying down 10,000 kilometers of fiber-optic cable this year in implementation of LTE or Long Term Evolution technology. This would bring high-speed data to mobile phones and other devices. A Globe product called Tattoo Torque is powered by GPON or Gigabit Passive Optical Network which uses fiber optic technology. The maximum speed of Tattoo Torque is 150 Mbps. Smart Communications have also implemented LTE internet. Now, they are still doing tests especially in Metro Manila to have an improved internet connection which is planned to be launched in the middle of 2012. Smart LTE is several times faster than the average wireless and wired connections being offered today in the country. Wireless LTE could bring as much as 42 megabytes per second of connection. The Filipinos would surely experience smooth and faster connection. Downloading, uploading and sharing files will be done in just minutes and even in seconds instead of hours. The famous way to connect to the internet nowadays is through Wi-Fi or Wireless Fidelity. This technology allows the people to connect to the internet anywhere without using those hassle wires. All they have to do is...

...These days it is almost impossible to imagine our life without computers and the Internet. They influence many aspects of day-to-day being of every person not only at home and in spare time but also in education process. So, have these new technologies involved in relations between students and teachers and changed them cardinally? The first thing that should be noted is the Internet and computer technologies were begun to be applied practically in educational organizations not long ago, so there still appear problems in their proper usage. This brings us to the question of how people have been able to pass their experience to the next generations and create such sophisticated inventions. The answer is clear for me: owing to best approach in education, precisely “from teacher to student” by any means such as oral lectures or from books. Anyway, there has been the most important component-human interaction. Nowadays, in the century of computer technologies our homes, schools and many other places are computerized. The great impact of that we can see when we are studying. For instance, one has access to different recourses, libraries and educational information via the Internet. What’s more it has become much easier to continue studying without stopping and get knowledge about anything you are interested in. I cannot help saying that computer technologies bring us the chance to study distantly communicating with a teacher through the Internet. Furthemore, this kind of......

...Internet What started off to be a useful and friendly way to get connected with people around the world is turning into a major problem. The Internet caused many issues in today’s society in the last decade or so. With the advancement of technology, these issues are increasing significantly. Since the Internet was introduced, people are less likely to engage in leisure activities outside and rather stay inside, in front of their computer, where some might call it “internet addiction”. The article we have chosen is called “Don’t be a virtual ass, rush out this second and get a life” (Lunn, 2008). The article talks about a British couple, David and Amy Pollard, who got divorced because David “cheated” on Amy on Second Life, a virtual world on the Internet. Amy discovered that David had been paying virtual prostitute for virtual pleasures for his character, where Amy called it “unreasonable behaviour” and the “ultimate betrayal”, however David claimed he did nothing wrong. It is hard to determine who is right and who is wrong. According to Lunn (2008), he thinks that Amy might have been overreacted because a virtual world is just like an imagination, where it will never come true. Lunn (2008) also questioned what is considered “appropriate” or “inappropriate” in terms of Internet usage and is there a “line” between reality and virtual life? Since Amy spends as much time on the Internet as David, it might seemed to her that their virtual life is as important as their...

...Running head: INTERNET AND EDUCATION IS THE INTERNET A GOOD EDUCATIONAL RESOURCE STEPHANIE HUNT JULY 14, 2013 ENGL 101-D01 Summary In today’s society, students are relying more on the internet for their educational resources. The internet can be a valuable resource in certain situations; however, students should not rely too much on the internet as a resource. Students should use the resources the library has to offer such as books, newspapers, magazines. These resources are more reliable than most internet resources. Resources such as books, newspapers, and magazines are a better choice because they are supported by facts and reliable sources that can be verified. In Judith Levine article “I Surf, Therefore I am” (Salon magazine, 1997) Levine, says, “most of the data my students Net is like trash fish.” I believe she made this statement because she feels most of the information students acquire from the internet is not useful and reliable. Students need to make sure they are getting information from reliable sources. I am guilty of using an internet as a resource to study for a quiz and I did not do well on the quiz because some of the information was not reliable. On another note, the internet has been a valuable educational resource for me and other online students. University’s like Liberty University that offers online education is a great resource for adult...

...INTERNET There's a new technology that blooms in the modern civilization and that is the Internet. Internet is a new way of communicating, sharing memories, and connecting to other people. Bill Gates’ vision of an ‘Internet revolution’ and Jeremy Deller’s ‘steampowered Internet machine’ exemplify much of the contemporary discourse about the Internet and information and communication technologies (ICT). The Internet is widely thought to represent not just a new form of communication, but instead a new organizational form of modern society (Castells 2002) The imaginary of an ‘Internet revolution’ has been readily adopted in discussions of economic development. Development practice has always employed existing links and created links between developers and those who are being developed. Those links (e.g. roads or Internet connections) are not only integral to the actual implementation of development, but are also often justified as desirable in and of them. However, unlike past links between developers and developing, the Internet appears almost free of spatial constraints: any two computers can connect to one another irrespective of geographic location. INTERNET PRINCIPLES: * The Ability to Connect. The edge-dominant end-to-end architecture of the Internet is essential to its utility as a platform for innovation, creativity, and economic opportunity. * The Ability to Speak. The Internet is a powerful mass medium for self-expression which depends on the ability...

...Jeremy Alexander Jenkins January 25, 2014 Internet Essay Dr. Moira Maguire Word Count: 627 “Do students rely solely on the internet or should they use a balance of diverse kinds of sources?” Students use the internet for a variety of things such as entertainment, social needs, and very few times is it used as a dependable source. Although students don’t use it reliably, I believe that students should use a balance of sources. Internet and Library sources are both very useful in their own rights when utilized properly; however they both have their pros and cons. In this essay I will discuss the benefits and liabilities of using the two types of sources. Students who use a mixture of sources are more likely to have more valid and solid facts than a student who uses all sources from one place. The sources begin to become more repetitive and less factual when they are all retrieved from one place. This also makes it harder for the writer to put the sources into their own words creating a suspicion of plagiarism. The liability of the internet is that it is a place where anyone can create anything and put it on a forum for all to view, retrieve and use as a source. Just because something is put into a space doesn’t make it correct. Using caution and exercising good judgment can help prevent using a bogus source, but in contrast the internet provides an interactive multimedia experience that is not available with library sources. Sources from the internet are...

...Internet Mario Robles Com/285 July 13, 2011 Patricia Madrill Internet In my current workplace e-mails are non-existing, e-mails between our company members are avoided and communication is done through cell phone or radio call. Therefore, policies about Internet use are not available and not required in this stage of the company. However, if our company where to provide employees with Internet privileges I can see why they would want to implement Internet policies. With those policies the company enforcing them should be aware that employees would not be completely satisfied with about their privacy and think that their personal business is no longer personal. * What are the e-mail use, Internet use, and privacy policies at your job? * In my current workplace policies about Internet usage are not stringent, reason being everyone in the company has their own laptop. My company, after you have been with them for a year will give you a $1,000 gift card. This gift card is not just free money, it comes with two restrictions. The first restriction is that you should use 75% of this money toward the purchase of a new lap top, the second restriction is that the rest of the money has to be spent on a Verizon wireless card and a two-year subscription fee with a Verizon wireless vendor.

...The Internet is the global system of interconnected computer networks that use the Internet protocol suite (TCP/IP) to link billions of devices worldwide. It is a network of networks[1] that consists of millions of private, public, academic, business, and government networks of local to global scope, linked by a broad array of electronic, wireless, and optical networking technologies. The Internet carries an extensive range of information resources and services, such as mobile apps including social media apps, the inter-linked hypertext documents and applications of the World Wide Web (WWW), electronic mail, multiplayer online games, telephony, and peer-to-peer networks for file sharing. The origins of the Internet date back to research commissioned by the United States government in the 1960s to build robust, fault-tolerant communication via computer networks.[2] The primary precursor network, the ARPANET, initially served as a backbone for interconnection of regional academic and military networks in the 1980s. The funding of a new U.S. backbone by the National Science Foundation in the 1980s, as well as private funding for other commercial backbones, led to worldwide participation in the development of new networking technologies, and the merger of many networks.[3] The linking of commercial enterprises by the early 1990s marks the beginning of the transition to the modern Internet,[4] and generated a sustained exponential growth as generations of institutional,......

On that note, google chrome play a major role in providing feature such as; speed, signing in, simplicity, privacy, security and customization that enable you to make google chrome your own. However, rhetoric devices; such as pathos, ethos and logos also play a major role in social networking and internet as well. Why? Because they appeal to the audience’s emotion, convince the audience to reason logically and accept the credibility of people whom we admire. After watching “Google Chrome: Dear Sophie” commercial, its amaze me of how Sophie father have so much love for her and was able to capture every moment of her life from birth to first birthday, ski trip and thus her first giggle which really seem cute and adorable. In the first place, I felt sorry for Sophie being in the hospital and it was sadden to see her farther down. In other word not being able to function probably without his little Sophie. In like manner, I was really touched by the way Sophie dad record her growth and was able to email every remarkable moment to the future.

...Each new wave of technology produces new challenges to the present systems and ICT was no different. It often struggles with issues like privacy of the data of the citizens and consumers, security, protection of Intellectual property (IP), issues of freedom of expression as one gets a better platform to express. These issues among the others have to be settled in a fair way and they can’t be settled anymore by the government alone. So there have to be some mechanisms to put various stakeholders on a common platform, establish a dialogue between them and negotiate terms and come to a common decision that caters to the requirements of all the stakeholders such as private companies, internet service providers, civil society, governments, technologists etc. Instead of working in parallel, all the stakeholders can work collaboratively towards creating a platform for dialogue of all the stakeholders, finding out interests and concerns, bringing everybody together towards problem solving, rather than acting retroactively. It is common that governments very often get together with other governments and technical people very often get together with technical people but these separate stakeholders never come together to solve issues and work in a fair way towards decisions that are arrive conjointly. Issues ranging from digital divide to human rights. Issues of accessibility and how to bring the last billion on the internet. Privacy concerns, and concepts such as right to be forgotten.......
